1. Продукт бүтүп калдыview
The Dwyer Series WMT2 Multi-Jet Water Meter is engineered for commercial and industrial applications requiring accurate water flow measurement. Its multi-jet design ensures reliable performance and accuracy across a broad range of flow rates, including low-flow conditions. The meter is built for durability and minimal maintenance, even in challenging environments. It features a magnetically driven, hermetically sealed register that prevents leaks and fogging, completely isolating it from the water flow. A reed switch, activated by a magnet on the dial, generates a pulsed output directly proportional to the flow rate. This output is suitable for remote monitoring of flow rate or totalization and can be integrated with PLCs, counters, data loggers, and SCADA systems.

5. Орнотуу жана орнотуу
Installation of the Dwyer WMT2-B-C-11-1 water meter should be performed by a qualified professional in accordance with all applicable local and national plumbing and electrical codes.
- Жайгашкан жерди тандоо: Choose a location that is easily accessible for reading and maintenance, protected from freezing temperatures, and where the meter can be installed horizontally with the flow arrow pointing in the direction of water flow.
- Pipe Preparation: Ensure the piping is clean and free of debris before installation. Use appropriate pipe thread sealant on the 1" BSPT couplings.
- Механикалык орнотуу: Install the meter into the pipeline, ensuring a tight, leak-free connection. The meter should be installed in a straight run of pipe, ideally with at least 10 pipe diameters of straight pipe upstream and 5 pipe diameters downstream for optimal accuracy.
- Электр байланышы: Connect the color-coded lead wires from the pulsed output to your remote monitoring system (PLC, counter, data logger, SCADA). Refer to your system's documentation for specific wiring requirements. Ensure all electrical connections are secure and properly insulated.
- Агып кетүүнү текшерүү: After installation, slowly open the water supply to the meter and check for any leaks at the connections.
6. Иштөө нускамалары
Once installed and the water supply is restored, the Dwyer WMT2-B-C-11-1 meter will begin measuring water flow. The meter's register displays the totalized volume of water that has passed through it. The pulsed output provides an electrical signal (1 pulse per gallon) that can be used by external devices for remote monitoring and data logging.
- Reading the Meter: The main display on the meter face shows the total accumulated volume. Smaller dials may indicate fractional units for more precise readings.
- Pulsed Output: The reed switch generates a pulse for every gallon of water that flows through the meter. Connect the lead wires to a compatible device (e.g., PLC, counter) to record these pulses and calculate flow rate or total volume remotely.
- Агым багыты: Ensure water flows in the direction indicated by the arrow on the meter body for accurate measurement.
7. Техникалык тейлөө
The Dwyer WMT2-B-C-11-1 Multi-Jet Water Meter is designed for relatively maintenance-free operation. However, periodic checks are recommended to ensure continued accuracy and performance:
- Визуалдык текшерүү: Regularly inspect the meter for any signs of physical damage, leaks, or corrosion.
- Register Clarity: Ensure the hermetically sealed register remains clear and free of fogging, allowing for easy reading.
- Туташуу бүтүндүгү: Verify that all plumbing and electrical connections remain secure and free of corrosion.
- Тазалоо: If the exterior of the meter becomes dirty, wipe it with a damp кездеме. Катуу химиялык заттарды же абразивдүү тазалагычтарды колдонбоңуз.
No internal user-serviceable parts are present. Do not attempt to disassemble the meter, as this will void the warranty and may damage the device.
8. Кыйынчылыктарды
If you encounter issues with your Dwyer WMT2-B-C-11-1 water meter, consider the following troubleshooting steps:
- Агымсыз окуу:
- Check if water is actually flowing through the pipe.
- Verify the meter is installed with the flow arrow in the correct direction.
- Inspect for any blockages upstream or downstream of the meter.
- Туура эмес окуулар:
- Ensure the meter is installed horizontally.
- Check for air in the pipeline, which can affect accuracy.
- Verify that the flow rate is within the meter's specified nominal flow range.
- No Pulsed Output:
- Confirm that water is flowing through the meter and the mechanical register is advancing.
- Check the electrical connections of the lead wires to your monitoring device.
- Ensure the monitoring device is correctly configured to receive pulses.
- Туташуулардагы агып кетүүлөр:
- Tighten connections carefully, ensuring not to overtighten.
- If necessary, drain the system, reapply pipe thread sealant, and reassemble.
If problems persist after performing these checks, contact Dwyer Instruments, Inc. technical support for assistance.
